• Added "per-dot=" option to the -dots command, for setting the value-to-dot ratio. To represent 100 people per dot on a population map, you would use per-dot=100.
• Added "copy-fields=" option to -dots, to copy one or more data fields from the original polygon layer to the generated dot features.
• Added "multipart" option to -dots, which combines groups of same-color dots into multi-part features.
